What extensions do you think should be added. I, for one, want an extension that allows scratch to look at patterns on camera using AI, such as if there was some signature you would need to get into something, while still needing a real object. I also think they should add a scratch extension for not only size for an object, but also height and width blocks. Also, maybe they could add an extension for scratch to be able to read words on a camera and determine distance using the camera.
